Re: async dial problem

Which direction is the call going ? Into the 3700 or dialing out from the 3700 ? Please describe the dial process that is taking place. What kind of trunk are you using PRI, or CAS ? Capture debug cas or debug isdn q931 in addition to debug modem csm and debug modem to get a better look.
